The present invention generally relates to a protecting structure and, in particular to a protecting structure of uninterruptible power supply for preventing the uninterruptible power supply from a faulty operation.
2. Description of Related Art
Nowadays a traditional uninterruptible power supply is designed to switch a splitter into a normal loop status or a bypass loop status by controlling a switch of the splitter. However, power controlling device provides electricity to electronic instruments or production equipment through a splitter for choosing a proper loop and achieving an uninterrupted power supply.
A conventional uninterruptible power supply is designed to have a splitter on the outside of an electronic instrument or production equipment etc. The splitter has a switch, and the switch is provided with a switching element. When the switching element is not pulled, the splitter is in a normal loop status, and the electricity of the power supply device will be provided to the electronic instrument or production equipment from the normal loop. Furthermore, when the switching element is pulled, the splitter will be switched from a normal loop status to a bypass loop state, and the electricity of the power supply device will be provided to electronic instrument or production equipment through the bypass loop.
A conventional uninterruptible power supply has the following shortcomings: firstly, a sensor component of the switching element of the switch is provided with the splitter together so that the splitter is expensive; secondly, the splitter is installed on the outside of the chassis that a faulty operation might be happened; thirdly, as the splitter is installed on the outside of the chassis, an occupied space of the chassis is increased.
In view of the above drawbacks, the Inventor proposes the present invention based on his expert knowledge and elaborate researches in order to solve the problems of related art.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In cooperation with attached drawings, the technical contents and detailed description of the invention are described thereinafter according to a number of preferable embodiments, being not used to limit its executing scope. Any equivalent variation and modification made according to appended claims is all covered by the claims claimed by the present invention.
Please refer to FIG. 1, it depicts an explosion perspective view of a first embodiment of the present invention. The present invention provides a protecting structure 1 of an uninterruptible power supply device 9 for preventing the uninterruptible power supply device 9 from a faulty operation. The protecting structure 1 is used for an uninterruptible power supply device 9. The protecting structure 1 includes a chassis 10, a sensor 20 and a cover body 30.
The uninterruptible power supply device 9 could be a circuit breaker, a contactor, a relay or a splitter. The uninterruptible power supply device 9 has a switch 91 with a switching element 911, and the uninterruptible power supply device 9 can switch from a first position P1 to a second position P2 by pulling the switching piece 911 of the switch 91 for the uninterruptible power supply device 9 switching alternately between a first state and a second state, wherein the first state is a normal loop status and the second state is a bypass loop status. Besides, the uninterruptible power supply device 9 further includes a starting switch.
A side of a cabinet is provided as a chassis 10. The chassis 10 is composed of a supporting plate 11 and an enclosure 12. The supporting plate 11 has an opening 111, an installation hole 112, and a screw hole 113 (as shown in FIG. 2). The installation hole 112 is located between the opening 111 and the screw hole 113, and the enclosure 12 is extended from a periphery of the opening 111 of the supporting plate 11. The enclosure 12 has an opening slot 113 communicated with the opening 111, and the opening slot 113 has a port 131 away from a side of the supporting plate 11 (as shown in FIG. 2). The uninterruptible power supply device 9 is installed in the cabinet, and a switching piece 911 of the switch 91 is inserted in the opening slot 13 from the port 131. Moreover, the cabinet could be applied in electronic instrument or production equipment and so on.
The sensor 20 is inserted in the installation hole 112 of the supporting plate 11 and located on a side of the opening 111 of the supporting plate 11. The sensor 20 electrically connects with a power supply controlling module, and the power supply controlling module is electrically connected with the starting switch of the uninterruptible power supply device 9. Thus the sensor 20 electrically connects with the uninterruptible power supply device 9 by the power supply controlling module. The types of the sensor 20 could be, but not limited to, an infrared sensor or some other sensors having the same effects.
The cover body 30 includes a cover plate 31 and at least one blocking member 32. The cover plate 31 has a through hole 311 corresponded to the screw hole 113 of the supporting plate 11 (as shown in FIG. 2). The blocking member 32 is extended from a lateral side near the opening slot 13 of the chassis 10, and one side of the blocking member 32 away from the cover 31 can be inserted in the opening slot 13 of the chassis 10. The blocking member 32 can be embodied as, but not limited to a column, a hollow column or a bump etc. Furthermore, when the cover plate 31 covers the opening slot 13 of the chassis 10 and the switching piece 911 has changed from a first position P1 to a second position P2, the switching piece 911 will eject the blocking member 32 for that the switching piece 911 is aligned with the blocking member 32. In this way, the cover plate 31 will depart from the opening slot 13 to expose the opening slot 13.
The protecting structure 1 further includes a fastener 40. The fastener 40 is inserted in the through hole 311 of the cover plate 31 and screwed in the screw hole 113 of the supporting plate 11.Thus the cover plate 31 is fixed by the fastener 4. The fastener 40 is, for example, a screw.
Please refer to FIG. 4 and FIG. 5, they depict two schematic views showing the operating state of a first embodiment of the present invention. When the uninterruptible power supply device 9 is switched from the second status to the first status and the switching piece 911 of the switch 91 locating at the first position P1 or the second position P2 is switched to the first position P1, the starting switch must be manipulated so that the uninterruptible power supply device 9 can switch from the second status to the first status.
In operation, the switching piece 911 of the switch 91 is pulled back from the second position P2 to the first position P1 at first. At the moment that the cover body 30 covers the chassis 10, the blocking member 32 is located on a side of the switching piece 911 and the cover plate 31 can cover the chassis 10. When the cover plate 31 covers the chassis 10, the sensor 20 will receive a detecting signal emitted from the sensor 20 and reflected from the cover plate 31. The sensor 20 transmits a signal to the power supply controlling module, and the power supply controlling module commands the starting switch in a workable state. Now the uninterruptible power supply device 9 can switch from a second status to a first status by manipulating the starting switch, and the power supply equipment will process a normal mode working.
By a design of the blocking member 32, the cover body 30 cannot cover the chassis 10 when the switching piece 911 of the switch 91 is in the second position P2. Thus users can be reminded that the uninterruptible power supply device 9 has not switched from the second status to a first status, and a foolproof effect and a faulty operation prevention for uses can be achieved.
In addition, a situation that the power supply equipment connecting with the uninterruptible power supply device 9 will provide electricity to the electronic instrument or production equipment through the normal loop status and the bypass loop status at the same time can be avoided. And a short circuit or a damage of the electronic instrument or production equipment will be caused when the switching piece 911 of the switch 91 is located in the second position P2 and the uninterruptible power supply device 9 is in the second status. Thus an effect for protecting the electronic equipment or production equipment can be achieved.
Moreover, by a design of the sensor 20, when the cover plate 31 does not cover the chassis 10, the starting switch is in a non-work state. When the cover plate 31 totally covers the chassis 10, the starting switch can be switched to a workable state because of the sensor 20.
Therefore, a situation that the power supply equipment connecting with the uninterruptible power supply device 9 will provide electricity to the electronic instrument or production equipment through the normal loop status and the bypass loop status at the same time can be avoided. And a short circuit or a damage of the electronic instrument or production equipment will happen when the switching piece 911 of the switch 91 is located in the second position P2 or a faulty operation of the starting switch is made by users. Thus an effect of protecting the electronic equipment or production equipment will be improved.
Furthermore, the sensor 20 can be provided separately with the uninterruptible power supply device 9 by disposing on the supporting plate 11 of the chassis 10. An uninterruptible power supply device 9 without a sensor 20 can be chosen, and the uninterruptible power supply device 9 will be cheaper for cost-saving. In another aspect, the switch 91 is covered in the opening slot 13 of the chassis 10 by the cover plate 31 covering the chassis 10. Hence the switch 91 and the uninterruptible power supply device 9 will keep clean and away from environment pollution. And an effect of protecting the electronic equipment or production equipment will be achieved.
A housing of a cabinet is provided as a chassis 10. The size of the electronic instrument or production equipment installed with the uninterruptible power supply device 9 will be reduced because the switch 91 is disposed in the opening slot 13 from the port 131 and the uninterruptible power supply device 9 is installed in the cabinet. Besides, since the cover plate 31 is screwed with the chassis 10 by the fastener 40, the cover plate 31 will not detach from the chassis 10 when the cover plate 31 suffers an external force.
With referring to FIG. 6, it depicts a schematic view of a second embodiment of the present invention. This embodiment differs from the first embodiment in that the screw 113 of the supporting plate 11 is replaced with at least one engaging slot 114, and the through hole 311 of the cover plate 31 is replaced with at least one hook 312. The engaging slot 114 is provided on the supporting plate 11 of the chassis 10, and the installation hole 112 is located between the opening 111 (as shown in FIG. 7) and the engaging slot 114. The hook 312 is provided at a lateral side of the cover plate 31, and the hook 312 is latched in the engaging slot 114. The cover plate 31 will be fixed firmly in the chassis 10 by the hook 312 latched in the engaging slot 114. Hence the cover plate 31 will not detach from the chassis 10 when the cover plate 31 suffers an external force.
Please refer to FIG. 7 and FIG. 8, they depict two schematic views showing the operating state of a third embodiment of the present invention. This embodiment differs from the first embodiment in that the uninterruptible power supply device 9 is a circuit breaker, the switch 91 is a toggle switch, and the switching piece 911 is a trigger piece. When the switching piece 911 is pulled upward for switching from a first position P1 to a second position P2, the blocking member 32 will align and eject the switching piece 911, and then the cover plate 31 cannot cover the chassis 10. The switching piece 911 must be pulled downward to the first position P1 so that the blocking member 32 will locate on an upper side of the switching piece 911, thus the cover plate 31 can cover the chassis 10.
Please refer to FIG. 9 and FIG. 10, they depict two schematic views showing the operating state of a fourth embodiment of the present invention. This embodiment differs from the first embodiment in that the uninterruptible power supply device 9 is a fuse, the switch 91 is a lever switch, and the switching piece 911 is a lever. The switching piece 911 has a handing portion 9111. When the switching piece 911 is pulled downward for switching from a first position P1 to a second position P2, the blocking member 32 will align and eject the handing portion of the switching piece 911, and then the cover plate 31 cannot cover the chassis 10. The switching piece 911 must be pulled upward to the first position P1 so that the blocking member 32 will locate on a lower side of the handing portion of the switching piece 911, thus the cover plate 31 can cover the chassis 10.
Although the present invention has been described with reference to the preferred embodiment thereof, it will be understood that the invention is not limited to the details thereof. Various substitutions and improvements have been suggested in the foregoing description, and others will occur to those of ordinary skill in the art. Therefore, all such substitutions and improvements are intended to be embraced within the scope of the invention as defined in the appended claims.
